To atl whom 'it may concern.'

Be it known that I, GEORGE WV. Srinns, a citizen of the United States,residing at Caesar, in the count-y of Hancock and State of Mississippi,have invented certain new and useful Improvements in Cultivators, ofwhich the following is a specification, refer- 'ence being had to theaccompanying drawings.

This invention is an improved cultivator and subsoil plow adapted foruse for cultivating growing crops and also for use in stirring thesubsoil in the furrow behind a turning plow so as to break up thesubsoil without bringing` it to the surface, the invention consisting inthe construction, combination and arrangement of devices hereinafterdescribed and claimed.

In the accompanying drawings-Figure 1 is a side elevation of acultivator and subsoil plow constructed in accordance with my invention.Fig. 2 is a plan of the same with the handles removed. Fig. 3 is asectional view of the saine on the plane indicated by the line who, ofFig. 1.

The beam 1 of my cultivator and subsoil plow is made of iron or steelplate and is comparatively broad in its vertical dimension and thin inits transverse or horizontal dimension. The front end of the beam isslightly upturned and is provided with a series of openings 2 for theattachment of a clevis at any desired point. Formed with the beam and atthe end thereof is a rearwardly extending arm 3 which is oifset from thebeam, the offset portion 4 which connects the said arm to the beam beingat an angle of about 45o with reference to the beam. The arm 3 is formedwith a clamping member 5 which is integral therewith and bent forwardlyfrom the rear portion thereof and disposed on the inner side thereof. Ialso provide a detachable section 6 which is formed of iron or steelplate and has a forwardly extending front arm 7 to bear against the beam1, a laterally oset rearwardly extending arm 8 opposed to and spacedfrom the arm 3 of the beam, and a clamping member 9 which is formedintegral with the said arm 8 and is bent forwardly from the rear portionthereof, and disposed on the inner side thereof. The beam 1 and theportion 7 of the detachable section are provided with registeringopenings disposed one in advance of the other and through which a pairof clamping bolts 10 extend, the said bolts serving to clamp the sectionG to the beam and to also clamp the upper standard portion of a tooth 11between said beam and said section 6. The said tooth has a relativelythin standard presenting broad flat opposite faces to bear between thestandard 1 and the section G, and the upper end of the said standard isbent laterally at right angles as at 12 to bear on the upper edge of thebeam when the said tooth is in its lowermostadjusted position.

It will be understood from the foregoing` that the bolts 10 which clampthe portion 7 of the section 6 to the beam 1, also serve to eHectuallyclamp the standard of the tooth 11.between said beam and said sectionand admit of the detachment of the section so that it may be disposed tooperate to any desired extent in the soil.

A tooth 13 which is identical in construction with the tooth 11 has itsstandard clamped between the arm 3 and the clamping member 5 by means ofa bolt 14 which also serves to secure the lower end of a brace 15 to thesaid arm 3. A tooth 1G which is identical in construction with the teeth11, 13 has its standard portion clamped between the arm 8 and theclamping member 9 by a bolt 17 which also serves to secure the lower endof a brace 1S to said arm 8.

It will be understood that the teeth 13, 16 may be vertically adjustedas may be required, and that they may be readily detached and replacedby others.

The handles 19 have their front ends secured on opposite sides of thebeam 1 by means 4of a bolt 20. They are also secured to the upper endsof the braces 15, 18 by means of bolts 21.

My improved plow may be used for the purposes of a cultivator, and alsoas a subsoiler for operation in the furrows behind a turning plow so asto stir, loosen and lighten the clay and other subsoil without bringingthe same to the surface. Moreover, my improved plow is extremely strong,simple and durable and may be manufactured at slight cost.

I claim:

The herein described cult-ivator and subsoil plow comprising a beamhaving a laterally odset arm at its rear end, formed therewith, the saidarm having an integral forwardly extending clamping member at its rearend; a detachable section having a forwardly extending portion to bearagainst arms and the clamping members thereof, one side of the beam andfurther provided handle braces, and clamping bolts extending 15 with alaterally off-set rearwardly eXtendthrough said arms, said clampingmembers ing` arm having an integral forwardly ex and said braces, andserving to secure the tending clamping member at its rear end, a bracesto the said arms, and to also clamp front tooth having its standarddisposed bethe standards of the rear teeth between said tween the beamand the forwardly eXtendarms and said clamping members. 20 ing portionof the detachable section, elamp- In testimony whereof I hereunto affixmy ing bolts securing said section to the beam, signature in thepresence of two witnesses.

and also detachably and adjustably secur- GEORGE WV. SPIERS.
